310 Watt LED UFO High Bay | 45000 Lumens | 5000K | 277-480V

Product Overview

This 310 watt LED UFO high bay delivers 45,000 lumens at 5000K color temperature, operating on 277-480V input. The fixture replaces 1000 to 1500 watt metal halide systems and produces 145 lumens per watt with a CRI above 80.

The die-cast aluminum housing measures 13.8 by 10.9 inches and weighs 13 pounds. A polycarbonate lens distributes light at a 120-degree beam angle. The fixture includes a 5-foot power cord and an 8-inch dimming cord for 0-10V control connections.

This high bay is UL listed and DLC Premium qualified. The fixture is backed by a 5-year warranty.

Where This Product Fits Best

The 277-480V input voltage makes this fixture suited for commercial and industrial electrical systems. Facilities with existing three-phase service at these voltages can connect directly without additional transformers or voltage conversion.

The IP65 rating allows installation in areas exposed to dust accumulation and water spray from any direction. The IK10 rating means the housing withstands heavy impact, which matters in spaces with forklift traffic, overhead cranes, or other activity that puts fixtures at risk of contact.

With an operating temperature range from -40 degrees F to 113 degrees F, this fixture handles cold storage environments, unheated warehouses, and facilities without climate control.

Performance and Functional Considerations

At 45,000 lumens, this fixture provides output appropriate for replacing 1000 to 1500 watt metal halide high bays. The 5000K color temperature produces a bright, neutral white light commonly used in warehouse, manufacturing, and distribution environments.

The 120-degree beam angle provides wide light distribution from a single point source. The 80+ CRI supports visual tasks where accurate color rendering is needed for inspection, sorting, or safety marking visibility.

Rated lifespan is 50,000 hours at L70, meaning the fixture maintains at least 70 percent of initial output through that period. Power factor is 0.90 with total harmonic distortion at 20 percent maximum. Built-in surge protection handles transients up to 4kV.

Installation and Long-Term Use

The fixture supports hook, pendant, or surface mounting. The 5-foot cord provides reach for connecting to junction boxes positioned above the mounting point. A separate 8-inch cord handles the 0-10V dimming signal connection.

At 13 pounds, the fixture requires appropriate structural support but remains manageable for single-person installation in most situations. The black housing blends with typical industrial ceiling environments.

The die-cast aluminum construction and IP65 sealing reduce maintenance concerns in dusty or damp conditions. The IK10 impact rating means the fixture can remain in service after incidental contact without requiring immediate inspection or replacement.

How This Fixture Is Commonly Used

Facilities replacing aging metal halide systems use this fixture as a direct swap where electrical infrastructure already supports 277-480V. The immediate-on characteristic of LED eliminates the restrike delay associated with metal halide, which matters in spaces where lights cycle on and off throughout the day.

The 0-10V dimming capability allows connection to building management systems or standalone dimmers for output adjustment based on occupancy, daylight contribution, or shift schedules. A motion sensor is available as an accessory for occupancy-based control.

The wide 120-degree beam suits open floor plans where broad, even coverage from fewer mounting points is preferred. The fixture operates at 50 or 60 Hz, accommodating standard commercial power frequencies.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified.

The IP65 rating means the fixture is protected against dust ingress and low-pressure water jets from any direction. The IK10 rating indicates the enclosure resists impact equivalent to severe mechanical stress in active work environments.

We provide a 5-year warranty on this fixture.
